Process for finishing art goods



P33063338 FIEISHING ART GOODS.

No Drawing. Application filed May To all w/mm c't may concern:

Be it known that I, EDWARD Mont-IL- IL'UQGIUGR, a citizen of the United States, and a resident of lies Angeles, in the county of lies Angelcs and State of California have invented ne i and useful Improvements in Processes for Finishing Art Goods, of which the following is a specification.

This invention relates to an improved process for produciu g1 artistic finishes on art objects,furniture mantels, fixtures walls and the like.

The invention has for its main object to provide an economical process for pro; viding an artistic finish on art objects and surfaces of the above character that may be readily applied by practically unskilled persons.

It will be understood in the consideration. of the invention that a great demand exists for reproductions of art objects produced by skilled artisans in prior genera tions, particularly those produced during certain periods? or epochs of the history of art. The originals were constructed of iron, stone or wood and after years of use and exposure to the elements have acquired a characteristic appearance such that cannotbe ordinarily reproduced except by skilled artisans. l l here iron was the material employed the surface has become OXldized and pitted and therefore to faithfully reproduce the object great skill is required and the cost of reproduction including time material and labor becomes excessive. Where the material used was stone or a moulded plastic material the surface there of has taken on a roughened appearance and a characteristic color. It is therefore another object of my invention to provide an improved process or method for eco nomically reproducing an age worn surface characteristic of iron or stonejwhich process may be carried out by employing com.- men and inexpensive materials in the hands of unskilled persons without the use of other than readily handled tools or appliances.

.t will also be understood that certain colors and combinations of colors such were used extensively by peoples of previous times, as the Egyptians and Greeks, are in vogue because of their appeal. to the eye and because of their absence of conflicting or inharmonious tones or vibrations, the

psychological effects of which have long been recognized. I refer to so called live 1321. Serial No. 173,558.

It is therefore another ob'ect of m invention to provide a process for linishinp walls. ceilings and like areas in which the colors are not altered by the presence of oils and by which process the surface is given a roughened or pitted surface as in the case of imitation of antiqueiron or stone objects which proved to be particularlypleasing n' and does not have the appearance of mere painted plaster walls I rloi'iurther object of my invention is to provide a process applicable alike to prac tically all varieties of art objects and surfaces so the; persons unskilled in such arts my use the process without involving great expense while being assuredthat the colon ing matter used in the process will be thoroughly set by the process and will not read ily change or fade.

In carrying out my improved process I employ a plastic or cementitious material adapted to be applied in a paste form to a surface with a brush, trowel or other similar means. The material used for the purpose of forming a substantial base for the finish to resist ordinary wear should be preferably of an ino anic and non-combustible material and further having the character of an hydraulic cement. The material I find most advantageous for use in the process is that commonly 'lrnown as gilde s whiting, chemically known calcium carbonate.

The first step in the process consists in mixing the gilders whiting with shellac in suitable proportions to form a paste that may be applied to a surface and adhere thereto. While 1 specify shellac preferably, it will be apparent as the description of my process progresses that other material may be used in place of theshellac provided it contains alcohol, vegetable matter or other organic matter that will volatilize upon the application of heat and give rise to a gas or vapor of suiiicient pressure to force its way through the mass of which it forms a constituent.

Upon the mixture of gilders whiting (calcium carbonate) and shellac being applied to requisite thickness upon a surface the coating is then subjected to a high temperature preferably by the direct imping ing of a flame jet upon the coating. I have found that a blow torch is particularly advantageous to carry out this step in the processinasmuch as the heat is thus quickly applied at a high temperature and the products of combustion assist in more rapidly carbonizing-tl'ie plastic base.

The heat of the flame causes the organic matter in the shellac to "vaporize, particular-1a ly the alcohol, which vapors upon generating at suflicient pressure force their way outward through. the mass and escape. Bubbles in the coating are formed thereby and as thevapors escape the bubbles break, leav ing the requisite roughened surtace of 11 pearance peculiar to the prof ss and resern bling antique. and age worn surfaces. Coloring matter maybe addedto theni' fore application to the surface 0* face may be colored afterward.

the sury virtue of the application of: heat as in the former case the color pigments are well set or burnt in and in "the latter case, the roughened surf-ace assures of coloring readily adhering'to the surface.

It is apparent that I mayeinp'loy yarious materials having the characteristics of the tare be-V aboveand otherwise alter the process within the a 3 )ended claims without de )artin from the spirit and scope of the invention.

What I claim is:

1. The process for finishing art goods including coatino' the surface thereof with a mixture of calcium carbonate and shellac and subjecting thecoating to the flame of a blowtorch',

' 2. The process for finishing art goods including coating the surface thereof with a mixture. of a plastic or cementitious -ng1aterial and a binder containing,volatile ingredients, and sub ecting the coating to a flame .JBt.

3. The process tor 'firn'ish'ing art goods in EDWARD MUEHLBAECHER;
